Umm, I'm afraid that you're wrong. That's not how it works. It scans for the cache, decode it back into HTML form, scan the HTML codes and check for any malicious <script> or any other tag. If found any, the defender would block or prompt alot of messages before I can access that website next time. I do scans one time in fifteen days.

You're right. This is way above my comfort zone knowledge and experience wise. Kind'a scary, as I find there is a potential offsetting hacker use behind a sophisticated invention to keep things clean.
